1. A recent survey found that 64.7% of the population own their homes. In a random sample of 150 heads of households, 92 responded that they owned their homes. At the 0.01 level of significance, does that indicate a difference from the national proportion?

Answers

Answer 1

Given :

Possible chances, x = 92

Sample size, n = 150

Success rate, [tex]$p=\frac{x}{n}$[/tex]

                          [tex]$=\frac{92}{150}=0.6133$[/tex]

Success probability, [tex]$p_o$[/tex] = 0.647

Failure probability, [tex]$q_o$[/tex] = 0.353

The null hypothesis, [tex]$H_o:p=0.647$[/tex]

The alternate hypothesis, [tex]$H_1:p!=0.647$[/tex]

Level of significance, α = 0.01

Therefore from the standard table, the two tailed z = α/2 = 2.576

Since the test is a two tailed test,

we reject the null hypothesis, i.e. [tex]$H_0$[/tex], if [tex]$z_0$[/tex] < - 2.576 or if [tex]$z_0$[/tex] > 2.576

We use the test statistics z proportion = [tex]$\frac{p-p_0}{\sqrt{\frac{p_oq_o}{n}}}$[/tex]

[tex]$z_o=\frac{0.61333-0.647}{\sqrt{\frac{0.228391}{150}}}$[/tex]

[tex]$z_o=-0.8628$[/tex]

[tex]$|z_o|=0.8628$[/tex]

The critical value,

The value of | [tex]$z_{\alpha}$[/tex] | at los 0.01% is 2.576

So we got, [tex]$|z_o|=0.8628$[/tex] and | [tex]$z_{\alpha}$[/tex] | = 2.576

Conclusion :

Therefore, the value of [tex]$|z_o|<|z_{\alpha}|$[/tex] and here we do not reject the [tex]$H_0$[/tex]

The p-value : two tailed - [tex]$H_a$[/tex] : (p! = -0.86279) = 0.38825

Hence the value of  p(0.01) < 0.3883, so here we do not reject the [tex]$H_0$[/tex].

Why do you think the idea of the American frontier or "wild West" became such a popular part of the American identity?

Answers

Explanation:

The American frontier, also known as the Old West or the Wild West, includes the geography, history, folklore, and culture in the forward wave of American expansion that began with European colonial settlements in the early 17th century and ended with the admission of the last few western territories as states in 1912. This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist attitude known as "Manifest Destiny" and the historians' "Frontier Thesis". The legends, historical events & folklore of the American frontier have embedded themselves into United States culture so much so that the Old West, and the Western genre of media specifically, has become one of the defining tenets and prides of American national identity.

Answer:

Self serving bias, because he sees his team as better than it is

Explanation:

Joe is most clearly demonstrating self-serving bias because he sees his team as being better than it is. Thus, option A is correct.

What is an unfair call?

Unfair Calling coverage protects against losses resulting from an unfair calling by a government buyer or contractor of on-demand instruments, including bid, advance payment, and performance bonds, furnished in respect of a particular project.

Joe in this scenario is demonstrating a self-serving bias because he believes that his team is better than the other team. This has led to him questioning the actions of others involved in the game.

Such as the referees because he can't fathom the possibility that his team, and himself, were not good enough that day. In this Joe will be the one who will be feeling as the decision that is taken is unfair. Therefore, option A is correct.

Identify one nintheen century ideology that likely influenced the varioud forms of political activism referred in sorce 1

Answers

Hello. You did not present the source 1 to which the question refers, which makes it impossible for that question to be answered. However, I will try to help you in the best possible way.

The main ideologies developed in the 19th century were anarchism, liberalism and socialism. It is likely that the source to which your question refers, presents one of these ideologies, due to the great relevance that they presented in the 19th century.

Liberalism was originated by John Locke, Montesquieu and Adam Smith and was in favor of the division of political powers, maintenance of private property, the right to life and freedom of expression. In addition, this ideology denied the need for government intervention in the national economy or in the way industries and companies were conducted.

Socialism, in turn, defended the end of social classes, the valorization of the working class, the end of the exploitation of the working class by the ruling class, the devaluation of the rich classes and the end of poverty. Socialism was divided into Utopian Socialism and Scientific Socialism. Utopian socialism asserted that socialism was an idology that could be applied peacefully in society. Scientific socialism asserted that the problems of social class divisions would only be solved through research on these problems and their scientific analysis.

Anarchism believed in the same things as socialism, but it preached the total destruction of the government and the rise of the working class as government commanders and leaders. Anarchism fought any kind of government policy, which did not present the working class as the center of established policies.

industries used to treat the environment very poorly. Indeed, major industries around the world did not have any respect or consideration for taking care of nature.
